ROBERT M. BECK, OF CHAMBERSBURG, PENNSYLVANIA.

ENGINE-GOVERNOR.

SPECIFICATION forming part of Letters PatentNo. 441,738, dated December 2, 1890.

Application filed February 15, 1890. Serial No. 340,532- (No model.)

"bersburg, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Engine-Governors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

My present invention relates to certain improvements in governors for steam-engines, having for its object to make more perfect the construction of that class of wheel-governors for slide-valve steam-engines in which shaft and carries weighted levers that are pivoted within the wheel-rim, said levers beingconnected by links to the arms of a vibratory sleeve, which is mounted on the hub of the governor-wheel, and, connecting with a shifting eccentric having an arm, which is pivoted to said wheel, a governor of this class being described and shown in my former Letters Patent on steam-engine governor, No. 359,006, dated March 8,1887.

The present invention comprises certain improvements on the governor covered by said patent; and the invention may be said to consist, essentially, in the construction, arrangement, and combination of parts, substantial] y as will be hereinafter described and claimed.

In the accompanying'drawings, illustrating my invention, Figure 1 is a face view of a governor-wheel and accompanying parts embodying my present improvements.- Fig. 2 is a detail side view of one of the knee-pieces, on which the weighted levers are fulcrumed, and to which the spring devices are connected which governthe travel of said weighted levers. Fig. 3 is a plan view of'the shifting, eccentric. Fig. 3 is an end view of one of the knee-pieces. Fig. iisa longitudinal section of the eccentric. Fig. 5 is a detail view of one of 'the headed screws, which are used to adjust the bisectional die-box. Fig. 6 represents an end and side view of said box.

Similar letters of reference designate corresponding partsthroughout all the different figures of the drawings.

which is pivoted at a to permit the eccentric to swing over the engine-shaft B, said pin a serving to connect the arm A with the gov ernor-wheel C, which is securely keyed to the engine-shaft, so as to rot-ate therewith. 'A

A denotes the eccentric, having the armA,

sleeve or collar having two arms D D is mounted on the hub of the wheel 0, back of the eccentric, and is vibrated by means of links F F, that connect the arms D D with the free ends of levers E E, fulcrumed within the rim of the wheel and carrying adjustable weights E E. Q

' G G denote rods pivotally connected with the ends of the arms D D of the vibratory sleeve by means of pins 17 b,which pass through and connect together the arms D D, links F F, and rods G G, said rods G G being inclosed by springs c c coiled about that portion of the rods between the knees which support them and their outer free extremities. Said eccentric A also has an arm A to which is bolted or otherwise rigidly fastened the segmentgear 6, that meshes with the pinion f, keyed upon the shaft that carries the paddle-wheel g. All these parts are the same as those shown and described in 'my former patent above referred to, and are presented here simply for the purpose of explaining the nature and function of the governor-Wheel to which my present improvements are applied.

roceeding now to describe in detail the improved devices which form the subject-matter of the present invention, I will refer first to the knee-pieces H H, which are shown in detail in Figs.2 and 3,and are indicated in their proper relative position inside the governor-wheel in Fig. 1. These knee-pieces H H are suitably shaped and formed so as to' have a curved face, which may fit neatly inside of the wheel-casing, and theyare con-' structed with the projecting arm H and the journal or pivot bearing 72 They are also preferably bored with a couple of passages, through which pass the bolts d d, by means of which the knee-piece is securely bolted to the wheel-rim. The bearings h permitthe end of the weighted lever to be fulcrumed on the kn ee-piece. The projecting arm II is perforated to allow the spring-inclosed rod G to pass therethrough. Thus it will be seen that the knee-piece is so constructed as to carry in Fig. 6.

the end of one of the weighted levers, and also to support the spring devices which serve to govern the travel of the weighted levers. It is therefore a neat, compact, and simple coirstruction,wl1ereby the weighted levers are fulcrumed at the proper points within the rim of the wheel, and the other parts permitted to be situated in compact relative position, so that they may discharge their respective func: tions in the proper manner.

Anotherimportant feature in this case may be described as follows: The eccentric-arm A, at a point between the eccentric A and the pivot a,is formed with a rectangular or other suitably-shaped opening I of the proper size to receive the bisectional die-box J, as shown in Fig. 3, said box being illustrated in detail This die is preferably made in two parts or halves, for the purpose of taking up the wear. It receives the pin 70, carried upon a lug on the two-armed vibratory sleeve, so that in this way a connection is established between the vibratory sleeve and the shifting eccentric, whereby the movements of the former may actuate the latter. The halves of the die are adjusted by means of screws K K, (see Figs. 3 and 5,) said screws being located at each side of .thedie-box and held within passages within the eccentric-arm A. These screws are provided with round heads K, preferably formed integral with the screw. These heads K rest in contact with the dies, thus presenting sufiicient wearing-surface. The screws are held in place by means of the external jam-nuts Z. By having the die-box arranged in this way and regulated by means of the adjusting-screws K K, which have heads pressing against the sides of the die-box, a very close, firm, and neat adjustment is secured. and maintained, thus improving the arrangement of the mechanical parts and securing betterresults in the construction and use of the governor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, ism 1. The combination, with the governorwheel, the weighted levers, the eccentric, the two-armed vibratory sleeve connected with the eccentricarm, the links, and the centripetally-acting spring devices connected to the armed sleeve, of the knee-pieces secured within the wheel-rim and having bearings where the weighted levers are fulcrumed, and projecting arms whereby the spring devices are supported, substantially as described.

2. In combination with the wheel of the governor, a knee-piece II, perforated for the passage of the securing-bolts d (1, whereby the knee-piece is fastened to the wheel-rim, said knee-piece having the projecting perforated arm H and the pivoted bearing h, and serving to support the spring devices and the weighted levers of the governor, as specified.

The combination of the engine-shaft,t11e flanged governor-wheel secured thereto, the eccentric swinging over the shaft and having an arm pivoted to the wheel, the two-armed vibratory sleeve mounted on the hub of the wheel, the weighted levers, the connectinglinks between the armed sleeve and the weighted levers, the spring devices for governingthe travel of the weighted levers, and the knee-pieces on which the weighted levers are fulcrumed and whereby the spring devices are supported, said knee-pieces being firmly secured within the wheel-rim and having perforated projecting arms and pivoted bearings, substantially as described.

4. The combination, with the shifting eccentric and the two-armed vibratory sleeve carrying a'pin, of the bisectional die-box located within an opening in the eccentric-arm, said diebox receiving said pin, and the adjusting-screws K K, having heads K, which heads bear, respectively, upon the halves of the die-box, said screws being also provided with jamnuts 1, by means of which the screws are held in place, substantially as described.

5. The combination of the governor-wheel, the shifting eccentric having a pivoted arm slotted to receive the bisectional box or die, the headed adj usting-screws arranged in connection with said die, the two-armed vibratory sleeve connected with the eccentric-arm by a pin that enters the box or die, the weighted levers, the connecting-links, and the centripetally-acting spring devices connected to the armed sleeve, together with the knee-pieces having bearings where the weighted levers are fulcrumed and having perforated arms whereby the spring devices are supported, as described.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT M. BECK.
